Why Monitor Peracetic Acid Online?
Peracetic acid (CH₃CO₃H, PAA) is a powerful, residue-friendly disinfectant used across drinking water, food & beverage and pharmaceutical processes. Its concentration must stay within a narrow window: too low and disinfection fails; too high and you face corrosion, off-flavors and residual-chemical risk.
The Bebur BT6308-Pera peracetic acid analyzer provides continuous online PAA measurement and can directly drive automatic dosing control — adjusting flow rate, pump speed or valve position to hold the PAA concentration at its setpoint, cutting reagent consumption and raising process control quality.

How It Works
The PAA sensor is a membrane-covered dual-electrode system that automatically adjusts its potential to eliminate zero drift. Peracetic acid molecules diffuse through the selective membrane and react electrochemically, generating a current proportional to concentration. Temperature compensation is handled automatically by the integrated temperature sensor.
This design eliminates the need for additional reagents or buffers in water quality measurement, reducing operating costs. Calibration requires only a high-point (span) calibration — no zero calibration.
Key Features
Membrane Amperometric Sensor
Dual-electrode membrane sensor based on the amperometric principle, with automatic potential adjustment against zero drift.
Reagent-Free Operation
No chemical reagents or buffers needed — lower operating cost and less routine maintenance.
No Zero Calibration
Stable baseline design; calibration requires only a single high-point span adjustment every 1–3 months.
Unaffected by Detergents
Measurement is not influenced by cleaning agents present in the water — essential for CIP and bottle-washing lines.
Long Service Life
Membrane caps and electrolyte are replaceable consumables; sensor bodies in PVC-U/PEEK with stainless steel 1.4571.
Wide Media Compatibility
Suitable for drinking water, process water and brine applications across municipal and industrial sites.
